Embedded System for IoT in Rural : A Proposed Solution
Agus Mulyana
11:02
Embedded systems have an important role for the internet of things. This unit usually consists of a microcontroller, sensors, actuators and an energy source. For IoT in rural areas, it has its own challenges, due to unstable internet network conditions which can reduce system performance, wasteful energy consumption and can cause the system to malfunction. To overcome this, it is necessary to design embedded systems specifically to anticipate these problems

Why does the speaker argue that IoT systems for rural areas must use a three-tier architecture instead of a two-tier scheme?
A
Because a three-tier model puts an embedded gateway between devices and the cloud so it can manage intermittent connectivity, perform predictable local tasks, and securely relay data.
B
Because a three-tier model is always cheaper to build than a two-tier model in rural deployments.
C
Because a two-tier model forces every sensor node to run a full desktop operating system.
D
Because a three-tier model removes the need for local data processing and sends everything directly to the cloud.
E
Because a two-tier model requires constant cellular coverage which is legally prohibited in many rural areas.

Thanks for the presentation. Do you have more info on the Hexamesh topology you are proposing ? In general when running on battery and using LoRa, devices are not listening continuously because RX power is quite high. How would a quasi-mesh system work without always-on listening capabilities ? Also, for the message transmission have you taken into account the duty cycle limitations that LoRa suffers in some parts of the world (for exemple Europe) ?

Thank you for the question, so far the hexa mesh hasn't been developed with an algorithm for optimizing the battery / device resources, for outside Indonesia, I haven't done research that far
Nice presentation! I liked the microtalk format.
